Subject: Draft NPDES Permit Renewal
Permit NC0025011
Elizabeth City WWTP
Pasquotank County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Peel:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the monitoring requirement for zinc has been
removed from the permit [See A.(1)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total copper limits have been added to the permit and the
quarterly monitoring requirement has been changed to monthly monitoring [See A.(1)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards, total cyanide limits have been added to the permit and the
quarterly monitoring requirement has been changed to monthly monitoring [See A.(1)].
• To provide an opportunity for the City to develop a plan to assess sources of total cyanide
and total copper in order to come in compliance with the limits in Section A. (1.), a 3-,
year schedule of compliance has been added to the permit [See Special Condition A. (5.)
Schedule of Compliance for Total Copper and Total Cyanide Limitations].
• Based on Mercury TMDL evaluation showing all reported mercury values at levels< 1
ng/L, Special Condition A. (5.)Mercury Minimization Plan(MMP)has been removed
from the permit.
• Based on DWR Instream Conductivity and Fecal Coliform Monitoring Guidance, the
facility discharges 100% domestic wastewater so instream conductivity monitoring has
been removed from the permit [See A.(1.)].
• The facility components list has been updated to include the two clarifiers, grit
dewatering screw and gravity belt thickener in use at the facility.
• The City of Elizabeth City reported Total Nickel, and Total Silver at less than detection,
with detection levels< 10 µg/L, and< 5 µg/L respectively, in the Effluent Pollutant
Scans. The City's allowable discharge concentrations are 8.30 µg/L and
D North Carolina Department of Environmental Quality I Division of Water Resources
Q J/ 512 North Salisbury Street 11617 Mail Service Center I Raleigh,North Carolina 27699-1617
u. +rrtawa.m� 919.707.9000
0.10 µg/L for Total Nickel and Total Silver,respectively. DWR's laboratory identifies
the target Practical Quantification Limits (PQLs) for Total Nickel and Total Silver as 2
µg/L, and 1 µg/L, respectively. 15A NCAC 2B .0505 (e) (4)requires that all test
procedures must produce detection and reporting levels that are below the permit
discharge requirements and all data generated must be reported to the approved detection
level or lower reporting level of the procedure. If no approved methods are capable of
achieving a detection level below the permit discharge requirement (or allowable
concentration) the method with the lowest detection level must be used. The City should
use sufficiently sensitive test methods for all pollutants, including when performing
Effluent Pollutant Scans.
• As the dilution allotted to the Elizabeth City WWTP is based off of a dilution study at a
flow of 3.5 MGD, the Instream Waste Concentration (IWC) for the chronic toxicity
requirement has been revised to reflect the current 4.5 MGD permitted flow [See A.(3.)].
The revised IWC was calculated using the IWC confirmed by the dilution study for up to
3.5 MGD of flow and using no dilution for the additional 1.0 MGD of flow. Should the
Permittee decide to conduct a dilution study at the current flow, they can request
modification of the toxicity requirement.
• Some of the wording has changed in Special Condition A. (3.), Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A. (4.) has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed (2020, 2021, and 2022). In addition, at the
end of the Special Condition, 2nd species Toxicity Testing Requirements for municipal
permit renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)
internet application has been added to your NPDES permit[See Special Condition A. (6.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (1.)].
• Language has been added to Footnote 1 to account for influent, effluent, upstream and
downstream abbreviations [See A. (1.)].
• Regulatory citations have been added to the permit.
The NPDES Standard Conditions (Parts II, III, and IV) are not included with this draft. The latest
version is available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF
file.

If a permittee is unable to use the,eDMR system due to`a demonstrated hardship or due to the facility
being,physically located in an area where less than`1.0�percent of the households have broadband access,
then a temporary waiver from the NPDES electronic reporting requirements may be granted and
discharge'monitoring data may be submitted'on paper DMR forms(MR 1, 1.1,2,3)or alternative forms
approved by'the Director. Duplicate signed copies shall be submitted to the mailing address above. See
"How to Request a Waiver from Electronic Reporting"section below.
Regardless of the sub`mission.method,the first DMR is due on the last day of the month following the
issuance of the permit or in the,case of a new facility, on the last day of the month following the
commencement of discharge/
Starting on December 21,2020,the permittee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act(CWA) Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see"How to Request a Waiver
from Electronic Reporting"section below).

Permit NC0025011
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9),the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website resources to identify the initial
recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program)that is the designated entity for
receiving electronic NPDES data[see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each
